I'm about to start on a major program, which I expect to be some 32K in assembly. To save me getting some additional gray hairs I'm sniffing at BASIC for this project. But I need -SPEED- can't afford to loose much of it compared to a well-written assembler program. Can anyone say something about PicBASIC's execution speed and code effici

Built the 2 resistor serial link as shown in some pic basic PDF files, and I have had no problem with the 16f84 (1k for pic serout, 22k for serin) re-compiled the program for a 16f88, plugged chip in, data from chip to PC is ok but data from PC to chip is not being seen by the PIC. I have led's on the lines, both led's glow when data is moving, a

Hi, I have not programmed a pic in years, since about 99 when the 16cf84 was the most used around, and even then it was for simple slow things, ie door / window open-close etc with limit switches so no great master pieces. (oh and the usual light flashers for the kids) I now need to build a motor speed control, the motor is to be co

Hi, i am using "PIC Simulator IDE" from OshonSoft to compile and assemble my code for the 16F628. All is working fine. But I have got the problem, that when I want to have i.e. 50 Hz frequency output to one pin on port a, i never get the result I am expecting. I compute like this : clock frequency is 16 Mhz, so internal clock is 4MHz. If I

Does anyone know what frequency or protocol "payload" used by Radio Shack wireless products? I have tried to build the product for less but cannot come close. I know its all volume! If I can use Radio Shack sensors I will not need to go through FCC testing. If I know the frequency and if I know the payload I can possibly create a repeater to extend

hello, I have been tinkering with the 16x84 for several years learning a little bit of assembly. However, I find my self wanting to make more involved programs that would be very involved to make in assembly. The most popular alternative appears to be PicBasic Pro but it kills me to have to spend $250 (i'll admit it, i'm cheap). I am pretty familiar wi

Hi to the list, I just extended the support on our PICC compiler (now 8.05PL2), and when I select the midrange processor (HPDPIC ide), I get a table of PICs, with the right hand column clipped in half. They are are 16F8xx, and an 'L' (?), but I've had to guess on the processors. Anyone have the last column data? HPDPIC is workable, but I'm waitin
